Chat Now Review on treatment and utilization of bauxite residues Bauxite residue (red mud) is a solid waste produced in the process of alumina extraction from bauxite.
Bauxite Crushing & Grinding 4400 t/h Primary ABON Sizer, crushing bauxite 2500 t/h Secondary ABON Sizer, crushing bauxite World’s largest Rod Mills on Bauxite at Gove,Australia Bauxite Bauxite ore is the major mineral source for extraction of alumina and subsequently aluminium, the most abundant element found in the earth’s crust.
The Bayer process is not easily explained in brief. This method of obtaining alumina from bauxite ore is complex and involves a lengthy succession of chemical reactions, with the process varying slightly depending on the makeup of the unique source of bauxite ore. Crushed and washed bauxite ore must first go through a process to remove any
Bayer process, comprising grinding (L, B) and then digestion (N 2, A) of a bauxite by bringing it into contact with a sodium aluminate liquor ( 20 b, 120 b ). Digestion consists of forming a slurry ( 3 a, 103 ) that is then treated to separate insoluble residues ( 5 a, 105 a ) from the sodium aluminate liquor.
